"net/http"
)
func Cors() gin.HandlerFunc {
return func(c gin.Context) {
method := c.Request.Method
c.Header("Access-Control-Allow-Origin", "")
c.Header("Access-Control-Allow-Headers", "Content-Type,AccessToken,X-CSRF-Token, Authorization, Token")
c.Header("Access-Control-Allow-Methods", "POST, GET, OPTIONS")
c.Header("Access-Control-Expose-Headers", "Content-Length, Access-Control-Allow-Origin, Access-Control-Allow-Headers, Content-Type")
c.Header("Access-Control-Allow-Credentials", "true")
//放行所有OPTIONS方法
if method == "OPTIONS" {
c.AbortWithStatus(http.StatusNoContent)
}
// 处理请求
c.Next()
}
}
